Sentry Crash Report:

Description Dennis Schridde 2013-10-13 10:12:32 UTC 
Application: kontact (4.11.2)
KDE Platform Version: 4.11.2
Qt Version: 4.8.5
Operating System: Linux 3.11.4-gentoo x86_64
Distribution: "Gentoo Base System release 2.2"

-- Information about the crash:
- What I was doing when the application crashed:
I started Kontact and was about to open a mailbox, when I received a message about the email program being unable to aquire a lock due to a timeout. After clicking OK, Kontact segfaulted. (Note that this is different from a bug I reported just minutes ago, where Kontact *aborted* after I clicked OK: bug #325954)


- Unusual behavior I noticed:
The message box I received just before Kontact segfaulted:
---
Im E-Mail-Programm ist ein schwerwiegender Fehler aufgetreten. Das Programm wird beendet.
Die Fehlermeldung lautet:
Zeitüberschreitung beim Erhalten der Sperre.
---

Rough translation: Serious error in the email program. It will be closed. The error message was: Timeout while aquiring the lock.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

Comment 1 Dennis Schridde 2013-10-13 10:19:16 UTC 
Possibly related bugs:
* bug #325954: Same message just before the crash
* bug # - b.k.o search times out, and Kontact is not operational anymore, thus I cannot give you the exact number: Kontact leaves a process behind after being closed and thus cannot be opened again - maybe that is related to some locking mechanism?
Comment 2 Dennis Schridde 2013-10-13 10:28:04 UTC 
After restarting Akonadi (akonadictl restart), this did not happen again.

That was bug #227636.
Comment 4 Denis Kurz 2016-09-24 19:26:02 UTC 
This bug has only been reported for versions before 4.14, which have been unsupported for at least two years now. Can anyone tell if this bug still present?

If noone confirms this bug for a Framework-based version of kontact (version 5.0 or later, as part of KDE Applications 15.08 or later), it gets closed in about three months.
Comment 5 Denis Kurz 2017-01-07 22:43:04 UTC 
Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.0 aka 15.08), please open a new one unless it already exists. Thank you for all your input.
